On Tuesday, Justin Bieber had this message for fans eagerly awaiting some new music from the teen star: "oh yeah ... and i think LESS THAN A MONTH ... I'm gonna give you some #newmusic." Bieber is busy in the studio locking down features for his forthcoming Christmas album.

With rumored collaborations with Sean Kingston and Taylor Swift, as well as a confirmed track, "Falalalala," with Boyz II Men, Bieber is hustling to get the album done.

"He thought we'd be perfect for it," Boyz II Men's Shawn Stockman said of their work with the star. "And we went in and locked in."

On Wednesday, Bieber not only confirmed another guest for the album, the Band Perry, but also teased a secret one. "@thebandperry heard the final version of our song for the Christmas album!! Love it. glad to have you!" he wrote, before going back and forth with his manager, Scooter Braun, about that other feature.

"Wow. Just got an #epic phone call regarding @justinbieber xmas album. 1 of the most #Legendary performers ever is joining the album!!" Braun tweeted.

Bieber responded, "@scooterbraun cant believe it ... completely #HONORED. I think people are going to be shocked. I was. #christmas."

In addition to all the feature updates, Bieber revealed, "working hard on this #SOMEDAY shoot. they are playing my first single from the christmas album. what is the name of it again .... hmmmm ....."

Bieber apparently also has something big in store for fans this week. Braun only had this to say about it: "kinda hyped right now .... @justinbieber has something pretty wild in store for this week. #remix."
